Within-Host Comparative Genome Analysis: Pairwise Analysis by Body Site for 35 Individuals With Multisite USA300 Methicillin-Resistant Staphylococcus aureus Colonization in the Nares, Throat, or Perirectal Area

Body Sites	Mean SNV Difference (Standard Deviation)	Median SNV Difference (Range)
Nares–throat (n = 19)	4.2 (3.8)	3 (0–11)
Nares–perirectal (n = 27)	4.7 (6.4)	2 (0–25)
Throat–perirectal (n = 17)	4 (5.5)	2 (0–20)

Thirty-two individuals had nares colonization, 22 had throat colonization, and 30 had perirectal colonization.

Abbreviation: SNV, single nucleotide variant.
